JAMES M. HENSLEY, OF MOUNT VERNON, WASHINGTON.

STOMP-FULLER AND CAPSTAN.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed December 22, 1906. Serial No- 349,191.

To all whom it may concern:

Be it known that I, JAMEs M. HENSLEY, a citizen of the United States, residing at Mount Vernon, in the county of Skagit and State of Washington, have invented certain new and useful Improvements in Stump- Pullers and Oapstans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in log moving devices, stump pullers and the like.

, The invention comprises the production of a suitable frame, a drum mounted thereon, improved means for rotating said drum, and improved means for preventing said drum from unwinding.

The invention further comprises the production of a frame work, a drum mounted therein, improved mechanism for revolving said drum, improved means for throwing into and out of operation said mechanism, and means for holding said drum against reverse rotation,

and means for releasing said holding means.

The object in view is the production of a device that may be thrown into or out of operation as may be desired, and one that is adapted to draw in a cable for moving heavy objects.

Another object in view is the production of a drum, a mechanism for preventing the reverse rotation of said drum, a plurality of gears for rotating said drum, means for operating said gears, and a lever for throwing the same into and out of operation.

With these and other obj ects in view, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings:Figure 1 is a side elevation of a device embodying the features of the present invention, certain parts being broken away to Fig. 2 is a side elevation of a mechanism embodying the features of the present invention. Fig. 3 is a section of Fig.1 on line 3-3.

In timbered lands it has been found desirable to have machinery that will be simple in construction, and easy to be moved from place to place, and yet strong enough to move heavy logs short distances, pull over stumps and exert power on various matters in like manner. The present invention is designed to accomplish these results.

Referring more particularly to the drawings, the numeral 1 indicates a frame of any desired construction which has provided therein a crossbeam 2. Formed in the crossbeam 2 is a bearing as 3, and secured to part of the frame 1 is a bearing block 4. Mounted in the bearing block 4 and bearing 3 is a shaft 5 that is adapted to carry a drum 6 which has formed integral therewith or rigidly secured thereto a ratchet wheel 7. The shaft 5 is firmly secured to the drum 6 in any suitable way so that as the shaft revolves the drum will revolve therewith together with the ratchet wheel 7. Engaging the ratchet wheel 7 is a pawl 8 that is normally held in engagement therewith by a suitable spring 9. The pawl 8 is adapted to be forced out of engagement with the ratchet wheel 7 by a cam 10, as clearly seen in Fig. 3. Rigidly secured to the shaft 5 is a comparatively large gear wheel 11 that has its gear teeth formed slightly on an angle for engaging a comparatively small gear 12 which has its teeth formed slightly on an angle. The gear wheel 12 is loosely mounted upon a shaft 13 that is adapted to be rotated by an arm 14 which in turn is operated in any suitable manner as by having a horse secured thereto for moving the same. The gear wheel 12 has secured rigidly thereto part of a clutch as 15. The member 15 is formed with a groove 16 which is engaged by a suitable lever mechanism 17 for reciprocating the member 15 of a clutch 18. The lower part of a clutch 19 is rigidly secured to the shaft 13 and rotates therewith so that when the member or part 15 engages the part 19, the gear wheel 12 will be adapted to be rotated which in turn will rotate the gear 11.

It will be observed that the drum 6 and ratchet wheel 7 are positioned between two bearings, as 3 and 4, and the operating mechanism, as wheel 11, is positioned outside of the bearing 3. This will permit the making of a comparatively large gear wheel 11 without greatly increasing the size of the frame 1 and yet permit a strong and durable structure to be made.

Inoperation the device is moved to the place where the same may be needed and is secured to suitable trees or stumps, or if desirable stakes or pegs as 20 may be used to hold the device in position. After having the device firmly secured in position, a rope 21 which is adapted to be wound around the drum 6 is secured at its outer end to a log, stump or other load, and then the arm 14 is revolved which will in turn eventually rotate the drum 6 and wind in the rope 21. This will move the log or other load, or if it be a stump will pull over or pull entirely out of the ground the same.

By constructing a device according to the present invention, a comparatively light and simple mechanism is provided which is adapted for logging purposes, a stump puller, and other like work.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A device of the character described, comprising a frame, a crossbar mounted in said frame, a shaft mounted on said crossbar and part of said frame, a drum mounted on said shaft and rigidly secured thereto, means for preventing a reverse rotation of said drum, a power wheel rigidly secured to said shaft beyond said crossbar, said power wheel being of comparatively large size, a power shaft mounted in said frame at right angles to said first mentioned shaft, a comparatively small gear Wheel secured to said power shaft, a clutch mechanism for connecting said gear wheel to said power shaft and at the same time connecting said power Wheel and said gear wheel for communicating power from said power shaft to said power wheel.

2. A device of the character described, comprising a frame, a rotating drum mounted therein, a power Wheel for rotating said drum, a power shaft secured at right angles t0 the axle of said power Wheel, a wheel for communicating power from said power shaft to said power wheel, and means for connecting said wheel to said power shaft, said means comprising a clutch having one member -rigidly secured to said power shaft and the other member rigidly secured to said wheel, the member secured to said wheel being formed with a groove therein and a lever for engaging said groove for throwing said clutch into and out of operation. 7

In testimony whereof I afiix my signature in presence of two witnesses.

JAMES M. HENSLEY.
